Answer:

L=4.30cm

SA=  110.94cm^2

Step-by-step explanation:

Given data

Volume of box= 80 cm^3

We know that the volume of a box is given as

V= l^3

80=l^3

l= ∛80

l= 4.30cm

also the surface area of a box is given as

SA=2lw+2lh+2hw

SA= 2* 4.30* 4.30+2* 4.30* 4.30+ 2* 4.30* 4.30

SA= 36.98+36.98+36.98

SA= 110.94cm^2
